Abstract: Presently described are methods of making an article comprising providing a structured film (1100) comprising a thermoformable planar base (212) layer and a structured surface (116, 216) layer disposed on a major surface (1200) of the planar base (212) layer wherein the structured surface (116, 216) layer comprises a different organic polymeric material than the thermoformable planar base (212) layer, and thermoforming the structured film (1100) into a thermoformed article (1000). Also described are thermoformed and thermoformable articles.
